Those videos with tanks that have all the extra vacuum lines are of newer TJ's. I'm not sure if they changed evap. systems in 03 or 04. If you hadn't already planned to do it, I would take the tank out of the skid pan, clean out any debris and if needed repaint the inside before it all goes back together.Dropped the gas tank to fix a broken fuel line connector and replace the fuel pump while it is out. I watched 4 or 5 videos on how to drop the tank, and I guess I am lucky as I only have 2 lines, an electrical connector and the filler to disconnect. All of the videos I watched showed several other lines that had to be removed once the tank was dropped about 2 inches.

Anything else I should do for maintenance while I have the tank out?
Edit: also take a close look at the vacuum hoses and replace them as needed.
